    Nutrient management of mustard varieties under saline water irrigation
    (CCSHAU, 2019) Priyanka; Ram Prakash
    Several studies have been conducted on different varieties of mustard under the effect of mineral fertilizers and saline irrigation conditions. The experiment on “Nutrient management of mustard varieties under saline water irrigation” was carried out in rabi season of 2017-18 at Research farm, Soil Science Department, CCS HAU, Hisar. The experiment was laid out in a split plot design with three replications, with four mustard varieties in main plots (Kranti, Giriraj, CS-54 and CS-58) and three fertilizer doses in sub-plots [RDF (N, P and K @60:20:20 kg ha -1), 125% and 150% RDF] with application of saline water for irrigation (7 dSm-1). The results showed that the plant parameters like plant height, primary and secondary branches per plant, number of siliqua and seeds per siliqua showed significant increase up to application of 150% RDF under saline water irrigation. 1000-seed weight reported non-significant increase with increased fertilizer doses and recorded maximum in variety CS-58 (5.90 g) at 150% RDF. Oil content decreased non-significantly from RDF to 150% RDF and reported maximum under variety CS-58 (40.17% at RDF). Among four mustard varieties CS-58 recorded maximum seed and straw yield (22.89 and 88.33 q ha-1) at 150% RDF followed by CS-54, Giriraj and Kranti. Nutrient content (N, P and K) in straw increased significantly up to 125% RDF and remained at par with 150% RDF being highest in variety CS-58 followed by variety CS-54, Giriraj and Kranti, respectively. Na+: K+ decreased non-significantly from RDF to 150% RDF and mean significantly higher ratio was recorded in variety Kranti (2.85). Soil properties like pH, ECe and organic carbon reported no significant changes with respect to different varieties and fertilizer doses. Available N, P, K and S of soil after crop harvest increased significantly up to the application of 150% RDF and observed maximum under variety Kranti. The cationic composition of soil extract was observed in order Na⁺> Mg²⁺ > Ca²⁺> K+ likewise the anionic composition of soil extract was observed in order Cl-> HCO3-> SO42-> CO32-, respectively. Therefore, variety CS-58 reported better results with the application of 150% RDF under saline water irrigation.

    Development of processing technology for instant mango shake powder
    (CCSHAU, 2018) Priyanka; Rekha
    The present investigation ―Development of processing technology for instant mango shake powder‖ was conducted with the objectives to optimize processing technology for development of instant mango shake (IMS). Fresh and six months stored frozen pulp mango pulp had total soluble solids (19.56 and 16.39 %), acidity (0.41 and 0.43 %), ascorbic acid (6.96 and 5.73 mg/100 g), reducing sugars (5.79 and 5.93%), total sugars (13.24 and 13.79%), pectin (0.51 and 0.54%), total carotenoids (1.24 and 1.15 mg/100 g) and total phenols (42.33 and 39.67 mg/100 g) Mango pulp was blanched in microwave (2.00 min. /100 g at 900W). After blanching, the product was either freez dried, tray dried or microwave assisted tray dried. After drying, dried mango pulp was ground to powder, mixed with skim milk powder (SMP) and sugar in 32:26:42 ratio, packed in aluminum laminated and polypropylene pouches and stored for three months at room temperature. IMS1 (prepared from mango pulp, mixed with skim milk powder and freeze dried) and IMS2 (prepared from microwave assisted tray dried mango pulp) had moisture content (4.60 and 4.15%), crude protein (0.82 and 0.77%), crude fat (0.42 and 0.46%), crude fibre (0.93 and 0.89%), ash (1.47 and 1.45%), carbohydrates (96.27 and 96.42%), energy (393.93 and 393.93 Kcal), calcium (262.67 and 252.33 mg/100 g), ascorbic acid (5.75 and 5.01 mg/100 g), carotenoids (1.14 and 1.09 mg/100 g), total phenols (39.19 and 34.17 mg/100 g), bulk density (0.94 and 0.89 g/cm3)and dispersibility (86.87 and 82.93%) The most acceptable instant mango shake powder i.e., mango pulp mixed with skim milk powder and freeze dried had moisture (4.60%), protein (0.82%), fat (0.42%), crude fibre (0.93%), ash (1.47%), carbohydrates (96.27%), energy 392.90 Kcal and calcium (262.67 mg/100 g), ascorbic acid (5.75 mg/100 g), total Carotenoids (1.14 mg/100 g) and total phenols (39.19 mg/100 g) Moisture content, water activity, acidity, non enzymatic browning, total soluble solids, solubility index and microbial load increased while, pH and ascorbic acid of the all three instant mango shake powder variants decreased significantly during three month of storage. Cost of IMS powder ranged from `247.54 to 46.72/100 g. All the instant mango shake powder variants were found acceptable even after three months storage.

    Self-esteem, achievement motivation and academic performance of high school children
    (CCSHAU, 2018) Priyanka; Balda, Shanti
    Self-esteem refers to person's beliefs about his or her worth and value. Self-esteem is important because it influences individual's decisions. Achievement motivation is described as the need for performing well or the motivated for success and evidence by persistence or effort in the facing the difficulties. Academic performance as well as achievement both is the outcomes of education and the extent from which a student, teacher and the institution has accomplished their educational goals. The present study examines the relationship between self-esteem, achievement motivation and academic performance of high school children. The study was conducted in Hisar city and rural area of Hisar district. Total sample constituted of 240 adolescents, 120 from rural area and 120 from urban area, representing both the sexes in equal number. Self-prepared interview schedule was used to collect information on personal and socio-economic variables. Self- Esteem Inventory (Prasad and Thakur, 1977) was used to assess self-esteem of children. Rao‟s Achievement Motivation Test (Rao, 1974) was used to assess achievement motivation of children. For academic performance, percentage of marks secured in previous three examinations was obtained from school records. The results revealed that maximum percentage of high school children belonged to moderate category of personally perceived and socially perceived self-esteem. Irrespective of area of residence and sex of children, self-esteem of majority of high school children was high followed by negative and balanced. Majority of children had moderate level of achievement motivation. Majority of children from both the areas belonged to above average category of academic performance. There existed significant positive correlations between self-esteem (personally perceived and socially perceived) and achievement motivation and academic performance of children. Children with balanced and high self-esteem had high achievement motivation and performed better in academics than those with negative self-esteem. Results further revealed that socio-economic status of family was strong predictor of self-esteem and achievement motivation of children.

    Assessment of multiple Intelligence of school going boys
    (CCSHAU, 2017) Priyanka; Chhikara, Sudha
    A person can be most successful in a profession when the same is according to his or her abilities and interest. The different domains and disciplines valued by different cultures exert a tremendous influence over how one's intelligences develop, and to what extent they are mobilized. Focus these days is on designing educational experiences for students that demonstrate and explore how they are smart in the synergistic environment of a community of learners. The present study was accompanied with the aim of assessing the multiple intelligence levels of school going boys and to study the cultural differences in the levels. For this, 200 boys in age group of 6-8 years from rural and urban areas of Fatehabad district of Haryana state were selected. The data were collected with the help of standardized Multiple Intelligence Tool and a questionnaire for human ecological factors by Dabas, R. 2000. The results of the investigation elucidated that majority of the respondents were found to be having average levels of intelligence for all the nine components of multiple intelligence. Significant differences were observed in the mean scores of boys from urban area for linguistic, logical-mathematical, intrapersonal, naturalistic and existential intelligences whereas in rest of the intelligences i.e. Musical, Bodily Kinesthetic, Spatial, Interpersonal, no significant variations across rural and urban setting emerged. The results explained that all the aspects of multiple intelligence were significantly associated with human ecological factors of the respondents.
